+ * anonpgpid.d - anonymous memory paging info by process on CPU.
+ * Written using DTrace (Solaris 10 3/05).
+ *
+ * This scripts may help identify which processes are affected by a system
+ * with low memory, which is paging to the physical swap device. A report
+ * of the process on the CPU when paging occured is printed.
+ *
+ * $Id: anonpgpid.d 8 2007-08-06 05:55:26Z brendan $
+ *
+ * USAGE: anonpgpid.d # hit Ctrl-C to end
+ *
+ * FIELDS:
+ * PID Process ID
+ * CMD Process name
+ * D Direction, Read or Write
+ * BYTES Total bytes during sample
+ *
+ * NOTES:
+ *
+ * This program is currently an approximation - often the process when writing
+ * pages to swap will be "pageout" the pageout scanner, or "rcapd" the
+ * resource capping daemon.
